My first AMD card was the Radeon 6770. It did it's job well. Now I'm using the Gtx 650Ti. Surprisingly here in India this was more expensive than the Radeon 7790 which was a bummer. After using Nvidia drivers I see no difference between AMD and Nvidia in terms of drivers. The TXAA for Nvidia and adaptive vsync are good features. Apart from that AMD is all god. The Radeon 7970 was the best buy option here by a huge margin. OP your in the right direction. I can understand how badly your Gtx 560Ti was holding you back as my gpu is more or less the same as the Gtx 560Ti and I game at a resolution of 1366x768. Wouldn't want to buy a new monitor without buying a new gpu.
